How should i solve this using an algebraic equation

artcher [175]

House price = down payment + mortgage x number of months

430,000 = 250,000 + 2,000x where x is number of months

To find number or months solve for x
430,000 = 250,000 + 2,000x

Subtract 250,000
180,000 = 2,000x

Divide by 2,000
x = 90 months

12 months in one year
90 = 84 + 6 = 12 x 7 + 6

7 years and 6 months

Look at the formula for the volume of a cylinder below.

scZoUnD [109]

$h = V / ( \pi r^2)$

Okay, so we already have the volume equation for a cylinder here.
$V = \pi r^2 h$
Since we need to find the height(h), we need to basically isolate it in the equation. To do that we just have to divide both sides by (pi * r^2), where we end up with:
$V / (\pi r^2) = h(\pi r^2) / (\pi r^2)$
then
$V / ( \pi r^2) = h$
$h = V / ( \pi r^2)$
